Design of Torpedo Wake Homing System for Higher Trajectory Accuracy

College of Mechatronics and Automation, National University of Defense Technology, Changsha 410073, China

摘要

摘要: 为了提高鱼雷尾流导引弹道的准确性, 该文对尾流自导设计中的3个关键问题进行了理论分析。首先, 提出了一种累计比较法用以形成尾流检测标志, 克服了尾流边缘随机变化导致的尾流检测标志不准确; 其次, 利用鱼雷进出尾流时刻的坐标值对尾流导引中的尾流走向和尾流宽度进行了计算, 使鱼雷入尾流后尽可能的沿尾流走向航行, 形成双波束导引, 较传统方法计算更加简单有效; 最后, 介绍了尾流中断层对鱼雷弹道的影响以及克服鱼雷在尾流断层中错误导引的方法。分析结果表明, 该方法可以有效提高弹道导引的准确性。

Abstract: Three key problems in wake homing design are analyzed theoretically to improve the accuracy of torpedo trajectory. Firstly, a new method for forming wake detection sign by comparing the cumulantion in a time period is presented to solve the inaccurateness caused by the randomicity of wake. Secondly, the orientation and the width of the wake a re calculated by using the coordinates of the points w here torpedo entering and leaving the wake, thereby the torpedo can run following the wake orientation with simpler and more effective way than the conventional methods. Finally, the effect of the wake break on guidance and trajectory is introduced, and the corresponding technique to avoid the misguidance is presented. Analysis results show that the present scheme can improve the accuracy of trajectory guidance.
